To further save battery power, select the following options in the Energy Saver pane of System Preferences:

ÂSet your computer to modify its processor speed based upon the required amount of processing activity.

During periods of high processing activity, your computer will automatically switch to a higher processing speed. To check this setting, open the Energy Saver pane of System Preferences and click Show Details to see the settings. To automatically change processor speeds, choose Battery Power from the “Settings for” pop-up menu, click Options, and choose Automatic from the Processor Performance pop-up menu. (To set your computer to use its highest processing speed at all times, choose Highest from Processor Performance pop-up menu.)
